Description When two adjacent single degree of freedom (SDOF) structures dynamically well separated, connected by appropriate viscous damper (Passive Control), their response to the horizontal loads reduced significantly. The soil-structure interaction change the performance of connected structure system. In this paper the influence of soil properties and damping characteristics on connected structure system is analyzed. The introduction of soil-structure interaction requires a mathematical model for the foundation and surrounding soil. The governing equation of equilibrium have been formulated. A range of soil properties and soil damping characteristics are chosen which gives broad picture of connected structure system behavior on influence of soil-structure interaction. The soil damping characteristics have major influence, but poisson’s ratio has a minor influence. It is concluded that the response of connected structure system on soft soil are more critical than those supported on very stiff soils. Various other energy dissipating systems to connect the adjacent structures to control the response are suggested.
